An effective Lagrangian for ηN interaction in nuclear medium is deduced from the chiral perturbation theory. The energy, effective mass and optical potential of η mesons as functions of nuclear density are obtained. Our results show that there is strong attractive η nuclear interaction at normal nuclear density, and in-medium properties of η depend strongly on the off-shell term which is determ...
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
introduction: nowadays, science mapping is considered an excellent technique for decision-makers to find solutions for problems in research planning and development. in this work, we aimed to depict a science map of “radiology, nuclear medicine, and medical imaging” in iran. methods: all publications indexed in thomson reuters web of science database in the fields mentioned above with at least ...
A new Skyrme-like energy density suitable for studies of strongly elongated nuclei has been determined in the framework of the Hartree-Fock-Bogoliubov theory using the recently developed model-based, derivative-free optimization algorithm pounders. A sensitivity analysis at the optimal solution has revealed the importance of states at large deformations in driving the parameter-ization of the f...
